The North Side
The trailhead from the north is the more famous way to get to the summit. The main route to the summit, the YDS Class 1 Cal Magnusson Trail is a fairly straight forward way to reach this summit. The trail remains at a constant moderate pitch and climbs a little over 1000 feet in 1 mile. There is a small wire on part of the trail to assist guest on one small washout section. There are no scrambles or even any severely steep terrain, but just a trail with a constant grade and with switchbacks from start to finish. This constant terrain and good elevation gain over such a short distance is the reason it is one of the preferred trail running routes.
There is also an alternate trail that leaves from the same trailhead. This trail known as the Goat Trail, has one real steep section but has a good view of the town of Enumclaw. This trail is not advised in wet, slippery or muddy conditions. It is very steep in spots and the footing is poor in sections. Both trails eventually reconnect as they get closer to lead to the true summit.
